I know your not still using the infamously buggy My eGallery but if you wanted to with GD thumbnails and your server isn't as old as this addon.
Find in modules/My_eGallery/imageFunctions.php
replace function RatioResizeImgGD() with this one.

Code:

// GD Library
function RatioResizeImgGD($src_file, $dest_file, $newWidth) {
global
   $gallerypath
;
// find the image size & type
if(!function_exists('imagecreate')){return $src_file;}

$imginfo = @getimagesize($src_file);
switch($imginfo[2]) {
   case 1: $type = IMG_GIF; break;
   case 2: $type = IMG_JPG; break;
   case 3: $type = IMG_PNG; break;
   case 4: $type = IMG_WBMP; break;
   default: return $src_file; break;
}

switch($type) {
   case IMG_GIF:
      if(!function_exists('imagecreatefromgif')){return $src_file;}
      $srcImage = @imagecreatefromgif("$src_file");
      break;
   case IMG_JPG:
      if(!function_exists('imagecreatefromjpeg')){return $src_file;}
      $srcImage = @ImageCreateFromJpeg($src_file);
      break;
   case IMG_PNG:
      if(!function_exists('imagecreatefrompng')){return $src_file;}
      $srcImage = @imagecreatefrompng("$src_file");
      break;
   case IMG_WBMP:
      if(!function_exists('imagecreatefromwbmp')){return $src_file;}
      $srcImage = @imagecreatefromwbmp("$src_file");
      break;
   default: return $src_file;
}

if($srcImage){
   // height/width
   $srcWidth = $imginfo[0];
   $srcHeight = $imginfo[1];
   $ratioWidth = $srcWidth/$newWidth;
   $destWidth = $newWidth;
   $destHeight = $srcHeight / $ratioWidth;
   // resize
   $destImage = @imagecreatetruecolor($destWidth, $destHeight);
if (function_exists("imagecopyresampled")) {
imagecopyresampled($destImage, $srcImage, 0, 0, 0, 0, $destWidth,(int)$destHeight, $srcWidth, $srcHeight);
}else{
   imagecopyresized($destImage, $srcImage, 0, 0, 0, 0, $destWidth,(int)$destHeight, $srcWidth, $srcHeight);
}
   // create and save final picture

   switch($type){
      case IMG_GIF: @imagegif($destImage, "$dest_file", 100); break;
      case IMG_JPG: @imagejpeg($destImage, "$dest_file", 100); break;
      case IMG_PNG: @imagepng($destImage, "$dest_file", 100); break;
      case IMG_WBMP: @imagewbmp($destImage, "$dest_file", 100); break;
   }

   // free the memory
   @imagedestroy($srcImage);
   @imagedestroy($destImage);

   return $dest_file;
}
else
{
   return $src_file;
}
}
