[TYPO3-UG UK] Help with scaled image crop gallery display

[Alan Ansell]

I did post earlier, but I think my question was too general and
unclear for anyone to really help.
What I wish to do is to use the ability of the image handling to
crop image thumbnails on a gallery page 'on the fly' by
scale-cropping non-regular formats into a single sized box.
I seem to feel that I should be adding the .width = "y"c.height =
"x" kind of property of the IMG_RESOURCE cObject.  - something
like "page.10.subparts.content.table.imgResource >" Is this
correct, or am I just going in completely the wrong direction?
Is it as simple as adding one or two lines like this to my
template file? Or do I need (hence I need help) to write a little
script to parse the entries from the image content element table
and display the results?
My site is a simple one and is derived through following all the
examples in the documentation. It is derived entirely from the
template_1 in the tutorial and all presentation is now under css
So my entire template script is exactly that given in the modern
template building tutorial. All I have since done, is to start
afresh, with no included templates, and include the standard
<content(default)> under "includes" and then edit them to remove
the bits that I don't need.
Thanks, Alan
