Could it possibly be this:

It sounds like ModLayout may be sending premature headers. Can you
disable this in your apache config and test?

FAQ entry: Apache ModLayout

If you use mod_layout with Apache, make sure it is disabled for gallery
files. Gallery sometimes sends binary data back from a php file, so
adding a header or footer to these requests will corrupt the data!

After adding the following lines to your apache config, it should work:

----------------------------------------------------
# Disable layout header and footer for Gallery2
LayoutIgnoreHeaderURI /path/to/gallery2/*.*
LayoutIgnoreFooterURI /path/to/gallery2/*.*

# PHP Gallery2 overide Layout
<Directory /path/to/gallery2/>
LayoutHeaderOff
LayoutFooterOff
</Directory>

PROBLEM SOLVED!

Thanks guys for all your help to get to the bottom of it.

The problem was in fact because of APACHE MODLAYOUT which corrupted the
outputed image by redisplaying the page as text.

cheers!
