I have detailed text images and their thumbnails look the same. I would like to  create my own thumbnails instead of the thumbnails generated. Is this possible?

Hi my friend!

I'm afraid that you can't do it with this version of sig pro!
We create the thumbs and we rename them with a specific name!

Also, you can just replace the thumbs that the sig pro create
with your thumbs but must keep the thumbs name that sig pro gives!

Thank you!

I have tried replacing the thumbnail files in the temp folder but the changes do not take effect and the thumbnails appear to be refreshed regularly (looking at file creation date/times in this temp folder).

Any more ideas?

hi my friend!

check this post for the bug

the thumbnails appear to be refreshed regularly

and retry to replace the thumbs with yours!

also you can modify the linewithif you don't want the cache checking!

Thank you!

The closest I could find was this...

// create thumbnails

if (file_exists($tempfolder.md5($_images_dir_.$name).$format) && filemtime ($tempfolder.md5($_images_dir_.$name).$format) + $cache_expire_time * 60 > time()) {

I should just remove

+ $cache_expire_time * 60 > time()

This is a hack - i needed to achieve the result fast to verify I could use SIG Pro. 

Edit the sigpro_engine.php file in the /mambots/content/plugin_jw_sigpro/ folder and replace the GenerateThumbFile($from_name, $to_name) function with this one. 


Below your sig_image folder ({gallery}sig_image{/gallery}) create a folder called thumbnails.  Copy your main images to this new thumbnail images folder and edit or resize them as required maintaining the same filenames.  When you run a page with {gallery}sig_image{/gallery} the new thumbnails are generated from the new thumnails folder content whilst the main pop-up images are generated from the sig_image folder.

Important - before using the modified function you must make sure you delete all current pre-generated images from the temp folder.

This code has no error checking in to make sure the thumbnails folder exists or indeed the images - it is quick and dirty but it works so maybe you can tidy it up and make it useful.  I am new to joomla and PHP - hence the noddy code!


  // generate thumb from image and save it
