    Hi people,

    I have recently noticed that the iPhone's mail application behaves a little funny when receiving image attachments.

    If I send an email from outlook with a 399KB image attachment and go to open it on the iPhone it claims the attachments size to be 547KB. If I then download and save this attachment the actual image is reduced to 451KB (still not the same as the origional file)

    If I open the emails attachment attachment straight on my computer it is as it was to begin with '399KB'.

    Does anyone know what is going on with the iPhone? Does it (negatively) compress the image when it receives and then again when it downloads the attachment?

    Cheers

    Rich.

    I think it converts to iphone format...( sizes it properly so u can see it on your iPhone)

    There are a million different factors that go into file size measurements. I wouldn't worry too much about it.

    It does not do that.

    Mmm I dunno about that, a JPEG should not change size unless compression has been applied, and if that's the case the image quality will be reduced as jpeg is a lossy format. The scenario in my opening post might suggest the iPhone negatively compresses the image twice before it can be saved...seems stupid!
