Multiarray localstorage eg

localStorage can only store strings, so you need to convert your array to a string.

myArray = [1,2,3]
localStorage.myArray = JSON.stringify(myArray) // '[1,2,3]'
x = JSON.parse(localStorage.myArray) // [1, 2, 3]

Actually,i have to store several rows of “…pic1.png”,to poulate between rows of Image obj,into something like

Dim a(3,5)
a = Array("","","","","","", _
                 "","","","","","",_
                 "","","","","","")
pic1 = Image1.src
localstorage.setitem(key(0,0),pic1),so on

B =localstorge.getitem(key(0,0))

,so on
I don’t know anything about sql…

This is important to understand.

If I’m understanding your query then…
Image1.src needs to be added to a picturebox control then saved to base64 string. eg
pb = PictureBox1.getContext("2d")
pb.addImage("Image1.png")
then (and give it time to load (is there an onload() event with picturebox anyone?))
picstring = PictureBox.todataURL("png")
then you put that string into an array element
MyArray[x] = picstring
then finally to save
localstorage.MySavedArray = JSON.stringify(MyArray)

Hope that is what you’re after.

Image control doesn’t have a .todataURL() function, as far as I know.
