Greetings! I have a grid of images like this: [gridimageshelp] What I need is each column to have its own selector column appended next to it where I can interactively select the cells (images) that I want. The selected cells will then be filtered downstream. I’m thinking of either 1 of these selection methods: An open-ended field where a user may write a nominal value between two options (e.g. writing a dummy score of 1 to select and 0 or nothing to leave the cell unselected), OR A tickbox function in which case choosing to tick the box selects the image next to it, OR A dropdown menu with an option of ‘Select’. (For this particular case, I have looked at this workflow but since I’m not a coder, I don’t know how to alter the code for my use case. Kindly help with this. Thank you. P.S. Would appreciate a workflow/idea that doesn’t involve looping since I’m working with a quite huge grid table.

Hi @badger101 , I think I have something for you that could be useable. You can use the Table Editor node!!! The changes from my previous example with the Table View are these 2 nodes: [image] The Constant Value Column simply adds a new column, which I called “Selection”. The Table Editor allows you to choose which column is editable - in this case I choose only the “Selection”: [image] And now I can edit any of the rows in the column: [image] [image] And that’s the result after: [image] Here’s the workflow: Interactive Cell Selector.knwf (28.9 KB) With regards to jpegs, you can convert to binary, then use the Binary Objects to PNGs node. Though the name of the node says “to PNGs”, it actually works for jpegs too. You can check what I did there: [image] Binary Object to Image KNIME Extensions Hi @sebversailles , I went back more carefully to what you wrote. The 2 nodes I suggested somehow work only with an image, not from binary objects, which I don’t understand why. I mean if they only take image as input, why do I need these nodes for if I already have the image? Anyways, for what you need, you can use the Binary Objects to PNGs node. I put a demo workflow quickly together for you. For my demo, I took some images and converted them to Base64, and then converted them back to imag…

For converting to PNG: does this help?
