Over all a really good product for how simple it was to setup. Thanks for the good work.
I had large images that required scrolling L/R and U/D under ORIGINAL_SIZE. Setting "$spgm_cfg['conf']['fullPictureWidth']" corrects the image views but not the slide show java script code. To correct change the fallowing php code in spgm.php.
Under the spgm_DisplayPicture function around line 1508 of file do the fallowing
1) Move the "// compute image dimensions" section above the "// Load pictures if slideshow mode is enabled" section.
2) In the "// Load pictures if slideshow mode is enabled" section change "print ' addPicture(" line to
print ' addPicture(\''.$_strPicturePath.'\', \''.addslashes($_strPictureCaption).'\', '.$iWidth.', '.$iHeight.');'."\n";
Alternatively you could do a specific config width, and height for slide shows but this is to complex for what I needed the program for.
Corrected file
