This should do it

Image1.Picture.Assign(Table1.FieldByName('foto').Value);

Correction

Image1.Picture.Graphic.Assign(Table1.FieldByName('foto').Value);

but you really dont need to use the graphic property, you can just use the picture property. for example

Table1.FieldByName('foto').Assign(Image1.Picture);
and vise versus

i write these code:

image1.picture.assign(table1.fieldbyname('Foto').value);
and
image1.picture.graphic.assign(table1.fieldbyname('Foto').value);

but in both cases mark these error:  (at time of run or compile)
"incompatible types 'Tpersistent' and 'Variant' "

Sorry about that, I wasnt thinking the correct answer is

Image1.Picture.Assign(TBlobField(Table1.FieldByName('Foto')));

This WILL work, I tested.
