Dear Support
I tried everything I could think of and went through your help forums and manual. I dont know were to search anymore and decided to join your forum. 
I can upload small to medium sized photos, but experience that the gallery does the following with large images.
Thumbnail displays ok, So I click on it. The next photo apears (resized verion - displays ok - click on it, Final photo displays as an X - not available. How do I fix this. I have another problem but will post it in another thread. 
I could not upload the image as its too large. Its 4,171,261 bytes in JPG format. and 1575 pix x 1272 pix, 250 dpi and 24 Bit Depth. ???
Hope you can help me out here.
