Hi Mitja,
Ah, that makes more sense now.... Hit the F1 key in CR Designer and then search for:
Making a static OLEobject dynamic
As Dell indicated there are a couple of ways to load the image dynamically. First one is to link the image to a file saved on the local hard drive, each time the report is opened the image will refresh. Note, only opening the report will refresh the image. It won't refresh if you rename the file and hit the Refresh button in the Designer.
Second way is to use a database field that has a file location in the field as text, CR will then look up the location and what ever is there will be in the report.
For example: C:\Users\Public\Pictures\Sample Pictures\Desert.jpg. Any picture called Desert.jpg will show up in the report when opened. You could call it CompanyLogo so it's generic.
Third option is as Dell indicated and you save the image to a database field. You can use a formula to determine which image to use.
Hope that's clear enough?
