Multithumb mambot: mods to resize images, format text and strip redundant tags : iJoomla RSS Feeder

I've been struggling with image handling in RSS Feeder, but some amended code handed through a support ticket seems to have fixed it. I've no idea how it fixed it, but it has.

Anyway, I use the awesome Multithumb mambot (http://tinyurl.com/3dbza3) for image handling on my site - I post 800 x 600 images by default, and this mambot turns them into a thumbnail for the article and links to the hi-res original.

There are two problems:

1. RSS Feeder is obviously ignorant of Multithumb and so just displays the full-size image in the feed.
2. Additional Multithumb modifiers (different size images, etc) require the use of the {multithumb} tag before the {mosimage} it applies to and RSS Feeder was displaying this redundant (for the RSS feed, anyway) information in the feed.

So, I've modified ijoomla_rss.php to fix this, and also to apply some basic wraparound text formatting to the image. The image resizing is a quick kludge, but short of getting RSS Feeder to talk to Multithumb, it's the best I can manage.

So, in ijoomla_rss.php at lines 650, 969 & 1295, replace the code:

Code:

for($i=0; $i<$introCount && isset($vect[$i]); $i++){
  $pic=substr($vect[$i],0,strpos($vect[$i],".")+4);
  $path=$mosConfig_live_site."/images/stories/".$pic;
  $img='<img src="'.$path.'" alt="" border="0" />';
  /// replace the first occurrence of string {mosimage} with $pic string
  $introt=preg_replace('/{mosimage}/', $img , $introt, 1);

}

//// the images from fulltext ###
  for($i=$introCount; $i<$len && isset($vect[$i]); $i++){
  $pic=substr($vect[$i],0,strpos($vect[$i],".")+4);
  $path=$mosConfig_live_site."/images/stories/".$pic;
  $img='<img src="'.$path.'" alt="" border="0" />';
  $fullt=preg_replace('/{mosimage}/', $img , $fullt, 1);
}

with:

Code:

for($i=0; $i<$introCount && isset($vect[$i]); $i++){
  $pic=substr($vect[$i],0,strpos($vect[$i],".")+4);
  $path=$mosConfig_live_site."/images/stories/".$pic;
  $img='<img src="'.$path.'" width="140" align="left" alt="" border="0" />';
  /// replace the first occurrence of string {mosimage} with $pic string
  $introt=preg_replace('/{mosimage}/', $img , $introt, 1);
  /// strip the first occurrence of string {multithumb}
  $introt=preg_replace('/{multithumb.*}/', "" , $introt, 1);
}

//// the images from fulltext ###
  for($i=$introCount; $i<$len && isset($vect[$i]); $i++){
  $pic=substr($vect[$i],0,strpos($vect[$i],".")+4);
  $path=$mosConfig_live_site."/images/stories/".$pic;
  $img='<img src="'.$path.'" width="140" align="left" alt="" border="0" />';
  $fullt=preg_replace('/{mosimage}/', $img , $fullt, 1);
}

I've added a width="140" and align="left" to the image attributes -- these values can obviously be anything you like.

I then look for the first occurrence of the {multithumb} tag and replace it with an empty string. It's pretty simple to amend the code to strip out all {multithumb} tags, too -- I only tend to use it once in the introtext.

All this suggests that it'd be trivial to improve RSS Feeder to include a predefined image size as a variable created in the back-end, so it'd be great to see this in a revision.

It'd also be great if the code could automatically strip out *all* mambot tags by default, leaving just the images.

Anyway, hope this is helpful to someone.
