[PHP] thumbnail problems

[Ninti Systems]

I've searched the archives on this and, while I have turned up some
tips, they don't seem to solve my problem.

I an building a website for an indigenous organisation where jpg images
are uploaded, resized to a standard format, and thumbnails also
generated at the same time (so that is two resizes for each image). Most
of the time this works OK, but there are a lot of pages where many
thumbnails are just blacked out, eg:

http://waru.org/arakuwaritja.php?p=63

On some pages, all images are blacked out, eg:

http://waru.org/arakuwaritja.php?p=36

whereas on others they're all OK, eg:

http://waru.org/arakuwaritja.php?p=43

The people in the field taking and uploading the photos insist that the
format, color depth, etc, is not changing from photo to photo, and I
can't discern any differences. Yet some work, some don't.

I read somewhere that memory limitations could cause this, but still, it
only happens sometimes and not others. We are on a crowded shared server
I think.

I'm use ImageCreateTrueColor() after checking with ImageIsTrueColor(),
otherwise just ImageCreate(). The initial resizes almost always work
(down from 640x480 to 400x300), with the thumbnails it is looking like a
50% failure rate.

Thanks in advance for any assistance.

[PHP] XSLT

[ninti]

I'm wondering if there is a way to include a query string parameter in an xsl
stylesheet.

I have a script that does this:

xslt_process($xsltprocessor,$xml,$xsl);

I'd like to include the value of a variable passed to this script via a query
string (eg. xmlscript.php?p=3 ), whereby the value '3' is passed to the xsl
stylesheet somehow. The xsl stylesheet should then only process section 3 of the
xml document.

I've played about with extra arguments to xslt_process and 
 to no avail.

Hope this is clear enough.

TIA

Mick
