Another person with V2 upgrade issues...
I am trying upgrade from v1 to v2 (licensed under hardawaydesign). Its not displaying the images -- only the image file names. It also is having all kinds of quirky issues in the admin console. For example it won't 'preview' galleries.
I noticed that the upgrade renamed folders in the 'images' directory from numbers to names. I saw similar entries in the database. I suspect the problem is related to this change
When I look at source code and other references to directories, sometimes it shows the 'named' directories -- other times it shows the 'numbered' directories.
I reverted back to V.1 it appears to be working. But since changes were made to the database, I fear I may now have problems with V.1 also.
