I'm building a new Template for Joomla 3.x and I want to make it easy for the user...
In the template manager I want an 'Upload Photo' file-field. This is no problem; just define it in templateDetails.xml.
However, I would like to save the photo with different sizes under different preset names. The template is a responsive design so I want to use this picture as a background-picture using different sizes for different screen sizes (css using @media (max-width: xxxpx) ).
I know how to use Imagemagick to do the resize and save files to the location I want. But for the life of me I can't find out how and where to:
- override the for the templateDetails (if necessary)
- override the form submit action
I found :Joomla Override Plugin but this seems to be outdated.
There is quite a bit of information on overriding on the net but not quite what I'm looking for.
Can anyone help?
