<div class="markdown_content"><p><a class="user-mention" href="/u/alrcastro/">@alrcastro</a> why you want to do this? Why do you need a fully dynamic image and want to handle the updating of the file etc?</p> <p>The reason why this is not working is you expect is that the imagepool is more static than you think to improve performance.<br/> Every image referenced in an imagepool and downloaded to the PLC will be added into a file e.g. application.imagepoolcollection.csv .<br/> The visu will only send a unique identifier for the image to the visu client (webvisu or targetvisu) which then will be mapped to a specific file on the plc.<br/> Then some caching happens to not always load the file.</p> <p>The feature "reload image when file changes" only applies to the IDE, but not to the PLC.</p> <p>Best regards,<br/> Marcel</p></div>

<div class="markdown_content"><p>Hi,<br/> maybe i missunderstand your requirement:<br/> think this works, if you change the image version property ( after you have changed the image in the /visu directory of the plc)<br/> -&gt; from release information on this issue:<br/> The image element now has a bitmap version property. The image will be reloaded when this version changes.</p> <p>Download a project with an image element.<br/> - Open Webvisu, Targetvisu or Remote Targetvisu.<br/> - Replace the image on the PLC with a different image.<br/> - The new image should be shown in the visu (if the image element version property is updated, see release note). </p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>@Marcel,<br/> I wanted that the images were not static, but rarther updated dynamically, either upon request or automatically by the browser itself through the already existing resource "reload image when file changes".</p> <p><a class="user-mention" href="/u/kislov/">@kislov</a>,<br/> I made a careful analysis of the Log which didn't recorded any mention of handling the image, whether tagged as <em>Info</em>, <em>Warn</em> or <em>Error</em>. I also tried to upload the updated images directly to the folder where Visu images are stored, and also did not work. BT, the jpeg image I am using opens on the browser where VISU is running, so the issue seems not related to the picture itself.</p> <p>I appreciate the kind help of yours, but I made the decision to give up, IMHO that shouldn't be any issue.</p></div>

<div class="markdown_content"><p>Just do a download. Images will be automatically transferred (if e.g. the image is used as static bitmap id).</p> <p>Best regards,<br/> Marcel</p></div>

<div class="markdown_content"><p>Hi. Check Device - Log.<br/> Also if you upload your image, I can try it with my plc.</p></div>

<div class="markdown_content"><p>I added a picture to the <em>ImagePool</em> having the attribute "Embeeded and LinktoFile" and I added the picture to the VISU area the same way as I did ith a static image (which works fine). However, the linked picture don't even appear right after the runtime get started.</p> <p>The picture is on the same folder and has the same name, either at the Controller's side, as well at the Codesys IDE side.<br/> None of them has space nor special characters.</p> <p>Is there any tutorial on this regard?</p></div>
