[gold] Here is an eTCL  script  
to estimate timing photo image loading under [pixane].
This script was largely derived from posting
of [Eric Hassold] on [The comp.lang.tcl newsgroup]
The timing statements were pulled from the 
program below after the timing info was calculated.
The impetus for the script was an [ask9] question about time 
of "loading  single image ...". 
My solution to a different application on Unix
some grey hairs ago was creating
batch thumbnails with [ImageMagick], before loading the
application script.
If one can work with thumbnails, a tcl or perl script
can use [ImageMagick] to thumbnail every image
in a directory or tailor to specific megabyte size.
Since now, I'm using etcl and [pixane] on an Acer Aspire pc notepad,
it might be desirable to establish some peg points or
timing results with the [pixane] image library.
The timing results with [pixane] are similar to those reported
for [ImageMagick] on a Pentium, [Fast image resizing] 
---- 
In planning any software, there is 
a need to develop testcases.
