Inserting images to an Excel sheet in Delphi

I have a question here, I have an application and I need to add images to it. I have tried:

Sheet.Shapes.AddPicture(G_V.Prog_Dir+'pic.BMP',false,true, 190, 10+(15*rowcount), 100, 100 );

it works just fine, but I don't want to give parameters, I want to insert pictures to specified (and parametric) cells because I need to add picture to the last column of the page; this excel needs to be printed I must mention that. So I tried:

Sheet.Range['E'+inttostr(rowcount),'E'+inttostr(rowcount)].Select;
Sheet.Pictures.Insert(G_V.Prog_Dir+'pic.BMP');

It looks OK at first sight, however I think this code links images to the sheet. For example, I send the created Excel to another computer and these images cannot be seen (I don't recall the exact error) and when I searched it, I found out that receiving computer needs to have images at the exact path. As a solution to this, "Sheet.Shapes.AddPicture" recommended but as I stated before, I need another solution here.

I didn't see anybody experiencing this kind of problem, I hope someone helps me out.
