Hi Bern;

The windows api cannot load up jpg files directly, you will need
some code to decode the jpg file and convert it to a DIB. Once
you have this in memory as a bitmap, then you can do what you want
with it. There are a few DLL's, I remember one was freeware, the
other from SmallerAnimals _ISSource21.DLL,(currently 750kb) that allow
you to read many formats and display. They work with RGB data, but
you can use their functions to create compatible DC's or valid bitmap
handles. You can also buy their source code ($75USD) and extract the jpg
routines and have a C++ buddy recompile a new smaller DLL.

Another image tool that I use is called IrfanView, the EXE is freeware
but the source code can be purchased. The author says everything was
written in pure C, no MFC, no C++, just C and the windows api. He
will sell you sections of his code for a very moderate price. If the
code is pure C/Win32api, it should be a snap to convert into PB and
compile into your main EXE.

Worth a look... www.irfanview.com

Regards,
Jules

Could someone point me in the right direction, please?

I would like to build an app that has several .JPG pictures in a directory which it can choose from (cycle through). It would load one picture each time it is run and display it on a dialog.

Is there any sample code for loading a .JPG at runtime and displaying it on a dialog?

Thanks...
