THere is no wizard, you will just have to code/design it yourself.
BUt, once you have the path to the image, it is no big deal to set the image source for your image control (be aware that I a referring to an image control and not an olebound control, an image control does not have a controlsource).
Say, you have a (modal)form with an image control on it and it is called from a method from your thumbnail form:
PROCEDURE ShowImage
LOCAL loForm, lcMyImageReference
lcMyImageReference = This should come from the place where you stored your image path
loForm = CREATEOBJECT('MyImageShowForm')
WITH loForm
.imgImageControl.Picture = lcMyImageReference && the path to your image
.Show()
ENDWITH
ENDPROC
BTW you can also download the source code of CrownBase and have a look how I did it, because I store the raltive path of the image as well and do something almost exactly like I stated above.
