I have also problems with the photogallery. I made my site in WebsiteX evolution 9 and exported it to evolution 10. My computer is windows XP SP3 professional.

Every photo in the gallery to  which I added a link  under the tab 'list' and then 'options' appears no longer on the internet or gives an image generator error. When I look to preview of the page in WebsiteX5 all seems well.

Also:

I gave a description to all the photo's in the galleries. In several cases I used an asteriks * in the description. These photo's in the galleries also no longer appear / show image generator images. Maybe this happens also with others signs like $ ^ & etc. When I look to preview of the page in WebsiteX5 all seems well.

I deleted all these photo's and renewed them but the error stays. 

I'm sorry to say, but with Evolution 10 I spend lots of hours because the program doesn't work as it should (shut down, update, help function etc, now the gallery). I bougt Evolution 9 in august 2012 you offered € 20 discount on upgrading to Evolution 10. In my eyes not much but okay, I bought it. However I am very disappointed. Your product was not good enough devellopped. Maybe Incomedia should think how to compensate. Especially Windows XP users.
