    Help!

    I made a bunch of files in Adobe Photoshop on a Mac. It's an older desktop without a wireless internet connection. The files were copied over with a flash drive and are on the PC desktop. But they won't upload to my Tumblr or Flickr pages.

    Here's where it gets weird:

    • The files all have the ".jpg" in the acutal file name extension.
    • The files are not large.
    • When the files are viewed on the PC desktop, there is a small multicolored bar at the bottom of every picture. Like, a pixelated color bar.
    • When the files are copied into the flash drive, a similar duplicate file with a period in front of the name is created. Example: A file named "Fathers Day Photo" also has a file named ".Fathers Day Photo". This duplicate file cannot be opened or viewed.
    • Weirder still, is when these errors were happening, I re-saved some of the files with the "Save For Web" function on the Mac. After moving these test files to the PC, they were all totally corrupted!

    Any help is much appreciated for this!! Thanks in advance.

    On the Mac try saving the jpgs as Tifs. When the Tif options window comes up make sure to select Ibm / pc byte order is selected.


    Make sure the jpgs are not locked or something.


    Also maybe try and email them to yourself somehow.


    Have you checked if you can open the files with another PC image browser? { just checking its not Tumblr etc which might be the issue }


    If you can open them on your PC try re exporting them again.



    That is about all I can think of for the moment :}.....I think your best shot is PS .Tifs though, then you can save as .jpgs again somehow on your PC.


    PS - If you are going to be re saving the same .jpg file over and over, then be aware doing so degrades the quality of the image. This is why a tif etc can be better to mess around as they do not degrade from being re saved.

    Photoshop jpgs are read differently on some systems. I forget if there's a way to export them as generic jpgs from photoshop, although I think there is. You're probably exporting them as 'adobe jpeg' (default) which I remember some progs having issues with. If you can open them with preview or something on the Mac and save them again from that app they will work, although you'll be adding another level of compression to them.

    Google 'adobe jpg not opening in windows' or something and you should find more info.

    Make sure that you're saving them in the RGB colour format, not CMYK.

    I may be remembering this incorrectly, I'm not sure. Definitly check that you're exporting in srgb and not adobeRgb or cmyk.

    Thanks for the tips thus far!

    A few things:

    • All of the files were saved as 8 bit, RGB color mode .jpgs.
    • When viewing the files in Windows Media Viewer, that little color box appears at the bottom of the image.
    • They are being attempted to be uploaded to a Tumblr page.
    • I could not upload them to an e-mail as attachments to send to myself.
    • Most obviously, my Mac desktip doesn't have internet capabilities, otherwise they'd have been uploaded from the Mac!

    Thanks again.

    In photoshop, choose "Save for web and devices" under "File" menu.

    Pics should be now ok for load to Flicker etc.

    I saved some test files under "Save For Web" in Photoshop. Those files could not upload to Flickr or Tumblr.

    I saved a test file as a .tif file and the files size is huge. This .tif file was successfully uploaded to Flickr. From there, I took a smaller .jpg copy of it from Flickr and successfully uploaded this to Tumblr.

    That's some time consuming digital re-rigging for merely uploaded a single photo!!! Is there another way or suggestion that anyone has? Hell, it is 2012 in the 21st century and it seems like there should be a better method to uploaded 200+ photos!

    Thanks again.

    Also, the file that did get uploaded to Flickr & Tumblr still has the small colored bar at the bottom of it, though this error is smaller than on the photos that could no be uploaded.

    Another thing, does anyone have insights as to why there is a duplicate file with a similar file name in flash drive when the main files are transferred to the flash drive (see my original posting about this).

    Check the JPG format is BASELINE

    There's a chance you're saving the JPGS as "optimized" or "progressive".

    When saving, in the JPEG options dialog box, check the box next to "BASELINE (STANDARD)", some photo websites refuse the optimized JPGS, and when they accept them sometimes rainbow colored artifacts appear at the bottom or in the middle of the image.

    The files starting with a "." are resource files, generally contains the file type, icon and some other info, are very small compared with the real file and invisible in a Mac, when you move the file to a PC or to a PC formatted disk, become visible, and many people get confused with it, in short words, just ignore them... if they annoy you so much, you can delete them without damaging the real file, they will be automatically created again in a Mac if needed.

    ----------

    BTW, Flickr has a Mac photo uploader app and a plug in for iPhoto, check the link

    Did that.

    My default setting for saving files in Photoshop is Baseline (Standard). I double checked, then re-saved the another test file just to be certain, then attempted to upload it to Tumblr with the same "file error" results.[/QUOTE]

    How big in inches are the images? Flickr crunches the files creating 3 or 4 versions at different sizes, but if the resolution is too big could have a problem dealing with the files...

    Try creating a 8x10 inches (or similar) image at 120 pixels per inch and upload it to see if it works.

    Sorry, I can't think on anything else that could be causing the errors other than the files are somehow getting corrupted when are saved to the flash drive used to move them from the Mac to the PC, I suggest reformatting the flash drive just to be sure.

    Good luck!

    Sounds like they're corrupted but it's impossible to say for certain based just on your description. Can you post a screen shot?

    What JPG settings are you using when saving?

    What exactly happens when you try? This is a very vague description and could be describing any number of issues.

    Those aren't really all that relevant. OSX creates them IIRC. I don't recall if they're thumbnails or something else but you wouldn't want to upload these anyway.

    Good point. Try transferring the images using another method/medium and see if the problem persists.

    Will do that shortly. I was so frustrated by this on Sunday, that I needed to step away for a day.

    JPG settings:

    • Embed Color Profile sRGB
    • Quality: 12/Maximum
    • Baseline ("Standard")
    • Resolution: 72 pixels/inch
    • Width: 8 inches, Height: 10 inches
    • Mode: RGB Color, 8 bits/Channel


    When I try to upload the file, it seems like it's working and goes through the motions where those "upload wave forms" are moving around. Then Tumblr gives me an error notice that says "the file is invalid or corrupted, please try again later."




    The flash drive was reformatted. Will see if this has effect on things.

    Once again, I truly appreciate everyone's input on this perplexing problem! Looking forward to resolving this (and getting a wireless card installed in the trusty G4 to avoid this and other similar compatibility issues again)!!

    A few years ago I got a little USB wireless adapter off Amazon for $18, they're still selling it, $9 now. :) It worked perfectly with my G5 iMac. I'd try that before getting an internal wireless card installed.

    (The white version costs $5 more...)

    Here is a screen shot for you. See the bottom right hand corner.

    Also, the flash drive was reformatted and it didn't change anything.
