Userform - Picture inserted into image1 control based on what is populated into textb

I have looked thru 20-50 threads on how to insert a picture into an image control on my userform that I have created. I need the image to correspond to the data that gets populated into my textbox6. The data that’s populated into textbox6 is based on what the user selects in the previous cascading combobox’s (in this case it’s a toner for a printer). I want the image of the printer to display on the userform. I for the life of me cannot figure out how to get this to work. I have a worksheet (picturelog) that has all my images in it but I cannot get the userform to reference it. Thanks for any help in advance on this issue.
