Any developer wants to take this project on? If interested, just PM me please.

I've worked on a native php project to achieve this action along time ago...

See: imageinterlace

But actually I don't know how hard it would be to implement this in Invision Power software.

I could have a look this week end.

@LDDG concidering my offer though.

Go for it @DawPi ... I said, I could.

@LDDG consider his offer, Dawpi is on of most talented & professional developers here.

 

Thanks for the offer guys but believe it or not, I did a quick research on Google and I figured it all out on my own!

All it took was 1 line of code in the Imagemagick.php file and now newly uploaded jpg attachments are saved/resized/thumbnailed as progressive jpgs. Exactly what I was looking for!

Thanks for the response and offer!

I realize this isn't an open source community but could you consider sharing what you did in an instructional post? I have Imagemagick enabled and wouldn't mind giving this a try. If you decide to create an instructional post please include the resources you found and where the files for modification are actually located!

Thanks for your consideration,
