>>>I have a table RESIDENT.dbf with picture embedded in a general type field Resimage.
>>>Command "APPEND GENERAL resimage FROM (picturefile)" is used to embed resident's picture.
>>>It works pretty good for .BMP pictures. However, .BMP files are much larger than .JPEG files.
>>>Embedded JPEG images are not displayed on form - just file name
>>>I tried to convert .JPG into .BMP, but the size of picture file became huge.

>>First:
>>DO NOT EVER USE GENERAL Field type, NEVER!!!!
>>That is mandatory :-)
>>When you insert into General field VFP keeps not only file, but the current user default application which handles that kind of files.
>>I remember we have problems even with BMP, because on my computer I have a Microsoft Imaging installed, but on others only Paint was available.

>>Just use a CHAR or if the path to picture is very lengthy use Memo, but NOT general.
>>Do not store picture in the table, keep only path to it.
>>If your application is multyuser you could copy that picture to a folder where everybodey have access (some subfolder of your data folder)
>>Then you could use:
>>thisform.Image.Picture = ALLTRIM(Table.Field)
>>at every change of the record pointer of your table.

>Great, it for sure will work
