Hi e2,
This got sidelined for a while, but dot and I have e had slightly different problems installing... she tried and got it working with your sample images, but when she tried to upload her own images, it didn't seem to work at all.
I started on a fresh install, first on her webhost, and then on mine, but in both cases, though the software runs fine and installs fine, it simply sits at the loading screen with the _/\_ wave symbol failing to load any images. Logging in works fine, as does uploading, and the pictures are all there in the gallery1 and gallery2 folders. I experimented with placing the software inside an e2gallerypro folder and in the root folder of the host at webfaction (dotm8rix.bleedingartsllc.com, right now its at the root) and correspondingly changing the URL's in the e2upload/xml/e2gallery.xml file to either be e2upload directly, or e2gallerypro/e2upload... The installation instructions and video really leave very little to chance, and yet I seem to be missing something very simple... permissions problem to the directory? I dunno. Would appreciate your help troubleshooting, I haven't had much time and don't know what to try next. I probably have 2 more customers for you too if I can get this working for her, but not until this problem's solved.
You also didn't respoond to the main question, adding preloading behavior to the gallery software... should just be a few lines of javascript I think, right? Thanks! If you need to contact me privately to discuss, I can be reached at brian at bleedingartsllc dot com. Thanks!
