Finally I solve my own questions.

Here I share the interin solution.

asWebImage
    | aStream writerClass imgType|
aStream := RWBinaryOrTextStream on: ''.
writerClass := ((Smalltalk includesKey: #JPEGReadWriter2)
        and: [(Smalltalk at: #JPEGReadWriter2) new isPluginPresent])
        ifTrue: ['jpg']
        ifFalse: ['gif'].
(writerClass = 'jpg') ifTrue: [writerClass := JPEGReadWriter2.
imgType := 'image/jpg']
ifFalse:[writerClass := GIFReadWriter.
imgType := 'image/gif'].


Thanks to who answer and who view Rosario images.
