Sorry don't know anything about flash 🙁.
I'm using Lightbox2 as to display my images. Gives a cool effect when you load the photo's.
Out of interest though:
I have 108 thumbnail images in a gallery of mine. They are 134px wide 80px high, at the moment they are 300 pixels resolution. Which I guess is too much, I have tried (using automator) to save them as a gif, with 80px resolution and 256 colors. However they are too poor quality to use.
Currently I've got them at 104KB, 150 resolution saved as a png. What do you think of this? This would mean 11232 KB (10.96785 MB I think though I'm probably wrong 😱).
I think that's too big would I be correct? What size resolution, format etc should I have my thumbnails?😕
