Is it possible to use pictures direct from web ?
i use now:
B4X: 
Dim img As ImageView = Tiles_JE1.AddImageResize("Im2", "b4j.png", xui.Color_DarkGray, 70dip, 70dip)
would like to use eg:
B4X: 
Dim img As ImageView = Tiles_JE1.AddImageResize("Im2", "https://www.mysite.com/my.png", xui.Color_DarkGray, 70dip, 70dip)
but as long i use last line my app crashes

you need to download the image first! Check this thread!

[B4X] SimpleMediaManager (SMM) - framework for images, videos and more

This is a simple to use, cross platform library, that does many complex things under the hood. The developer calls SetMedia with a placeholder panel and a url. The panel will show an image, video or animated gif (more formats will be added). 'Show a remote image / video / animated gif in...

If you unzip the Tiles_JE library you will find out the
B4X: 
Public Sub AddImage (pTag As String, pBitmap As String, pBackgroundColor As Int) As ImageView
sub uses
B4X: 
img.Bitmap = LoadBitmap(File.DirAssets, pBitmap)
So Tiles_je can not support for now Url links.. need to be modified

Not directly, but you CAN use online images by downloading them into a bitmap object and use that as sourche

Found a solution using:
B4X: 
Sub Globals
    Private ImageView1 As ImageView
    Private btnLoadImage As Button
End Sub

Sub btnLoadImage_Click
    Dim MyLink As String
    MyLink="https://www.b4x.com/images3/android.png"
    DownloadImage(MyLink, ImageView1)
End Sub

'Good example. Use:
Sub DownloadImage(Link As String, iv As ImageView)
    Dim job As HttpJob
    job.Initialize("", Me) 'note that the name parameter is no longer needed.
    job.Download(Link)
    Wait For (job) JobDone(job As HttpJob)
    If job.Success Then
        iv.Bitmap = job.GetBitmap
    End If
    job.Release
End Sub

Same way i will use also database saved pictures (the links)

The Tiles_JE library is intended as a "selection". Eg. as a replacement for B4XComboBox. That is, I choose from a menu that is represented by tiles. It is not intended as an image viewer.

It is not about imageviewer. Want to assign a custom small picture in the tiles. As you see it is not possible to include all icons or pictures in the app.
Pictures are saved in files on web or databases that point to an url or even base64 pictures that are hosted in db. There is a need to be flexible. So i checked your library and found it out myself.. Thank you for your reply. I fixed my code with some workaround.

But it is possible to add also an image from url as also from db (link) or base64 image here how i did:
B4X: 
    Public ppp As String = "b4j.png"
    
    Dim img As ImageView = Tiles_JE1.AddImage("Im1", ppp, xui.Color_DarkGray)   
    Dim MyLink As String
    MyLink="https://freepngimg.com/thumb/free/3-2-free-png-picture.png"
    DownloadImage(MyLink, img)
    
    Dim img As ImageView = Tiles_JE1.AddImage("Im2", ppp, xui.Color_DarkGray)
    Public bspic As String ="iVBORw0KGgoAAAANSUhEUgAAAGQAAABkCAYAAABw4pVUAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAAP9JREFUeNrs3LEJg0AUgOEYnMMZHCFWmccqM6RyBTNGqjiCIwQnyAan5ZFCECL4yPfDgQdXiB++wsIipXTScTp7BEAEBIiAABEQIAICREAEBIiAABEQIAICREAEBIiAABEQIAICREAEBIiAABEQIAICREAEBIiAANGPKqPdcHW9vzYcf0zPWw9k3y4bzg5Glv7uDWmy63pZXbYfl9Vm+zeQ/VsbQ5+IY8rIAiIgQAQEiIAAERABOWpl8Pv//lQyRgcp/GrcyBIQIAICRECACAgQAREQIAICRECACAgQAREQIAICRECACAgQAREQIAICRECACAgQAREQIAISt1mAAQB0ixTczXFPFAAAAABJRU5ErkJggg=="
    img.Bitmap = Base64EncodeDecodeImage.Base64StringToImage(bspic)

the download image code is in previous post.

You can use this directly to load images from URLs; it's more secure. If you want, you can adapt it so you send the URL and it returns the image. This is what I did for a solution.

Note
It's also included in SMM.
