Are you aware that the Lianja Web/Mobile Client supports image uploading. This does not require any code to be written on the client or server-side as it's all built into the Lianja Web Framework. All you need to do is add an "Image gadget" to a form section. Why write code when you don't need to!

You write images into an "object" or "graphics" column using REPLACE, not from a character column.

Replace field with "filename"

so if you are trying to use a fieldname contents as the filename put it into a temporary variable then use "&varname" in your replace statement.

No, (web apps) images need to be in a table.
In web apps (which he is building) you cannot just access files all over the disk for security reasons.

Q:
In VFP we used Thisform.LockScreen = .T. / .F.
A:
Lianja.lockscreen = 1
then
Lianja.lockscreen = 0
Give it a whirl. If I understand you correctly you want to disable screen updates, do something, then re-enable them.
A word of warning: Do not do this from the command window as it prevents all further input and output until it is re-enabled.
Also make sure your code that runs has no errors as you will not be able to interact with the UI while lockscreen is active.
