Taking images from Image Field (Joomla module)

Hello, I want to add a little new function to my Joomla module. My module shows a list of articles with a thumbnail, which is generated from the images inside the articles; I mean, my module takes the image from the article's text, resizes it and uploads the new resized image into a new folder. That new resized image (usually smaller than the original one), is shown as a thumbnail, near the title of the article. Currently, it only works as commented with the images inserted directly inside the article's text, but if you insert an image through the "Intro Image" or "Full Article Image" fields, it doesn't work properly: the module takes the image and resizes it with HTML; it doesn't resize the image generating a new smaller one, nor uploads it to a new folder. Simply, it uses the original image URL with HTML size atributes. RESUME: -------------------------------------------------------------------------------------------- So, I would want my module to detect, also, the images inserted inside the mentioned fields and work with them in the same way as it does with the images inside the text of the article: take the original image, resize it into the dimensions specified on module parameters, reupload the new image into a specific folder, and use the new image URL as the thumbnail. -------------------------------------------------------------------------------------------- The module "Featured Categories", for example, does it correctly: [login to view URL] The budget are 15$ USD. Please, leave a non automatic message if you are interested. Automatic offers will be ignored. NOTE: there are 5 layouts/themes inside the module. I only need it into the first one called "default". Thank you for reading. Best regards
