Jamie: I haven’t run into this issue but it’s fully possible something still breaks. Do you think you could send me the jpg that’s causing problems so that i can take a look at it?

Have you tried ’save for web’ in photoshop? It only saves the jpg data (stripping all meta data, thumbnails etc) and is less likely to cause problems. Still, even if you get it to work i’d like to take a look at the image that’s causing problems so that i can fix the class.

Barry: There shouldn’t be a max limit, but i’m sure there can be problems with this. Have you looked at the actual hex chunks of the image, trying to figure out what’s wrong? If you find out what it is, please let me know.

One common problem (that i mentioned above too) is that a jpg can contain multiple within itself. Try resaving the file with photoshop’s save for web.

I can also take a look at the image if you want, trying to see what may cause the problem?

Fantastic!

Do you know what the max size image you are allowed to load is? I got an 8400×600px image, loads but just shows a black box …

Sorry if this is off topic.
