returning to your 1/2 year ago attempt on pure tcl/tk attempt - "Image format png is not supported" - you just need

package require Img

#!/usr/bin/wish
package require Img
set fdata [read [open "/test/colorcube.png"]]
label .l1 -image [image create photo -format png -data $fdata]
pack .l1

[download]

Results is a popup labelled "Error in startup script" containing the text 

couldn't recognise image data while executing 
"image create photo -format png -data $fdata" 
invoked from within 
"labal,l1 -image [image create photo -format png -data $fdata]" 
(file c:\Tcl\test\test.tcl" line 4)

[download]

Which looks extremely similar to the problem I was having in OP of this thread. Namely, that it doesn't seem to be possible to pass image data in binary form using the -data option. Even when using Tcl directly.

It seems unlikely that if I ever get Tcl::Tk to install, that it would allow me to do this either.

All of which makes this whole Tcl/Tk subthread, and the time expended downloading and installing Tcl, a complete waste of time! Thanks.

And if that sounds ungrateful, it probably is. You see, I asked my question in the OP because I was trying to solve a particular problem. That problem remains unsolved.

I understand that as the author of Tcl/Tk, you are keen to promote it, but offering me a 'solution' that can never solve my problem is just a ****** *** ***** waste of my ****** time.
